Human carelessness and climate change are killing millions of animals. Gene editing could save them. Should we use it?

It wasn’t our intention that humanity would become the planet’s greatest evolutionary force; yet the fact that we are confronts us with an urgent and difficult question. Some animals, plants and insects can adapt but, for many, the pace of change is too great. Should we try to save them by deliberately intervening in their evolution?

The emergence of precision gene-editing technology like CRISPR-Cas9, which acts like a molecular scalpel so fine it can swap even single letters of DNA, has made a world of chimeric species possible. … [With] synthetic biology we could potentially save the world of the present, intervening in the evolution of vulnerable species so they can survive changing climates and collapsing ecosystems.

For some, the best we can do for nature is to leave it alone.
